Strange name for a Mexican restaurant, but so be it. This little gem on Federal serves some of the best Mexican in Denver, as well as tasty and GIGANTIC burgers. Always packed with returning customers, Jack n Grill doesn't disappoint! The tacos, freshly made in chewy homemade tortilla shells are insane!! Burritos are huge and beyond filling. While the decor is pretty bland and the lighting in the bar is way too bright (I enjoyed it much more before the renovation), the service is awesome and the food is tasty.
